What I claiinis asr ollows:

' 1. The combination with a brake beam and a brake head carried by the brake beam, and constructed with a hollow cylindrical part the interior whereof hasa regularly disposed series of devices, of a cylins drical block carried by the brake beam and fitting rotatably within the cylindrical part of thehead such'block havingan' annular flange formed rigidly upon one end a flanged collar secured upon the oppmite end thereof, such flanges being formed with correspond-' ing'series of equi-distant devices the devices of such series being disposed a distance apart different to the distance separating the devices of the head whereby the brake head can be secured in diflerent angular positions upon the brake beam.

2. The combination with a brake beam and a brake head carried by the brake beam, and constructed with a hollow cylindrical part the interior wherein has posed series of axially extending-grooves, of a cylindrical block carried by the brake beam and fitting rotatably within the cylindrical part of the head such block having an annular flange formed rigidly upon one end, a flanged collar secured upon the opposite end thereof, such danges being formed with corresponding series of equi-distant holes the holes of such series being disposed a distance apart different to the distance separating the grooves of the head, and a pin adapted to be inserted into a coinciding pair of such holes and one of the grooves in the head. whereby the brake head can be secured in d iflerent angular positions upon the brake beam.

The combination of a brake beam and a' brake headmounted concentrically on the beam, onepf said parts having an odd numher and the other an even number of locking members, and a key for forming a locking connection between a pair ofsaid members.

' 4. The combination of a brake beam, a brake head concentrically and ,rotatably adjustable connec-.

head comprising onone part an odd number and on the other ,part'an even number of relatively disposed 55 -oonnect1on between 'a pair of saidlockipg parts.

"' 5. The combination of a brake beam and a sac, 183

a regularly disocking parts, and a key for forming a locking brake head each embodying a sleeve constructed to fit concentrically one within the-- havin an odd num- Y other, one of said sleeves her and the other-an even nuniber of locking members, and a key forfdrming a locking connection between a pair of said members.

The combination-ofa brake bbam and 1a embodying a s eeve c'on the other, the sleeve on the head bein provided with openin s in chinteriorlylocated" loc faces between said openings, the sleeve on the E beam being provided with exteriorly located locking faces, odd and the locking faces, ing connection between a pair of said faces.

8. The' combination of a brake beam, a brake'head concentrically rotatably mountedthereon, and an adjustable connection be? tween said beam and head comprising on one part a plurality of locking members spaced apart and on the other part a plurality of locking members spaced apart a greater distance than .the members'onthe first part, and

one of said sleeves having an other an even number of said? and a key for forming a lock akey for forming a locking connection b'ej tween a pair of said locking parts.

9. The combination of a brake beam and a brake head mounted upon said brake beam,

one of said'parts having a number of locking. members differently s )aced from the lookinginembers carried by th aloeking connection between said e other, and a keyfcr fornnng members.

10. The combination of a brake beamand; -j

a brake head, locking devices onsai'dbea and head, being disposed at distances-apart differently spacedfrom thoseFseparating the locking d vices on thehead, p a locking connect on between said devices.
